Method Details

getInputStream

public InputStream getInputStream()

This implementation obtains the raw content from the MimeBodyPart using the getContentStream() method and decodes it using the MimeUtility.decode() method.

Specified by:

getInputStream in interface jakarta.activation.DataSource

Returns:

decoded input stream

Throws:

IOException

getOutputStream

public OutputStream getOutputStream()
                             throws IOException
